sEsTAvAsLAlf-BLE cos* i constructiomthis Vrigidity serving to render theheater .noiseless' notwithstanding the intermittent exhaust from the engine, .Which in aistr'ucture less carefully -bra'ced is found to produce an-'u'npleasant vibration. Here- .tofore this vibration has been overcome only by employing heavier' metal I.which forms an unnecessary4 expense and reduces the Also beneath 'the mid-sections of the tubes .94-9 'I fpreferably finsert a kind of i brid e 24 which may be of metal or'other suita le material, preferabl'y 'lhollow for k purpose of lightness, and having' notches snugly reeeiving the pipes, the exterior'of the bridge 'being Shaped and designed to fit 4 snugly into the pan. In' case the bridge be made'I of suitable shape and -size' I do not' i 80 find it necessary to. fasten it to'the pan in.

although serews or bolts canl be employed for greatersecu'rity. The engagement off'this bridge with the thin metal tubes damps their vibrations and -renders 85 the (lev-'ige .noticeably less noisy. I do not confine myself to this exact shape of bridge 2since any'kind of -clamp drawn'upon 'the tubes will secure the result. Also I do not 4 confine' myself to' a bridge engaging the pan, though I prefr .this construction since it quiets the pan as well as the tubes. However, with pans ofother constructions I am enabled to omit this feature. The employement of headers of the type described interposes between the inlet and outlet a plurality. ofpassageways of different lengthS, which tend, by interference' of sound impulses, to -render the exhaust substantially in the number vof tubeslhere shown being any' way,

suicientgto ov'ercome the'grcaterpart of the noise produced by engines of ordinary speed and construction. The inlet and .outlet lopenings in the header's 7 and 8 are ob- 5'5 served to be posit'ioned substantially midway of the header ends and the gases are caused to enter and leave the heads at an angle of 90 to the plane of the parallel arranged tubes." I have also found good re- 6.0 sults to flow from the. construction in the inlet header 7 of a dopendingtongue or Wed-ge 25 projecting substantiallj,r into the inlet aperture. Just the reason for lobtaining an advantage from this I cannot state, since it appears to be more than a mere -exhau'st pipe unobstiiucted, or

silent, lthe Variations of lengths 'eos splitting of the gasstrea'vm. My experience indicates that it has .some effect -in deadening 'the sound vibratiOnS, apparently by preventing any such .reverse direction of the same as should pass from one side of the radiator. to the other. Sucha header can also be 'used if desired at the outlet end, although no added advantages are produced thereby, wherefore I have shown 'in Fig. 4

.a plain header'at this point.

The inlet elbow 17 may be attached to its header in either direct or reverse position' 'depending upon the location of the heater relatively tothe engine exhaust pipe 30, and

preferably connectedA to said pipe by'I means of Vflexiblle metallic tubing 31. ,.At-

tachment to the exhaust pipe is preferably veffected by means of a saddle .32-clamped I 'upon the pipe 'by the aid of suitable'elps,

v 33-33. Said saddle is formed With ahoI-If low neck 34 receiving' the end of the tube '31. and constricted .'thereon by a suitable clamping screw 35. Traversing the neck 34 tangentially of Kthe pipe 30 is a pivoted Stein 36- to which is attached 'abutterflyvalve 37 and an Operating'- lever- 38, said.valve'-being -so arranged as either-to .close the-passage way throughthie' neck 34 leavnlgthe main' W n. opened to project a suitable distance across the exhaust pipe and'help -to'divert the' exhaust g'as'es vinto the theater.

I have shown the headerl' as an apertured .This saddle .can i' easily' be lapplied'to existing *machines by formed bracket'40 receiving' the 'pivoted stud' 41.'- The upper end of'this stud' carries an operatingarm 42 provided lWith abutton 43 which projects upwardly4 through asuitable slot in the plate 5.- The lower end of said stud *is deflected laterally as .at 44 for attachment to .the Operatingv rod-45 whose opposite end is articulated to the lever 38. The-lower face of the plate 5 is preferably formed with an arcuate rack 46, and the upper face ofthe' lever 42 is toothed as at 47 for -coperation therewith. yen, ;a.gement between said tooth and racl' being normally maintained by a spring 47 interposed between the arm and the bracke 40. With this .construction the heat ca: very readily be regulated even lby those wh never before saw'the device, theregulatin member being, directly associated with tl heater where it would naturally be lookr for, yet without dange'r of being dama if stepped on. The tooth 47 is 'prefera 'carried on a spring 48 set in a recess at t upper side ofthe arm." This renders -t engagement secure and'dimi'nishes the l bility of breaka'ge. The exhaust fitting may and sometir does consist merely'of an elbow,'but W some types of enginesl and With some spe I -thin cles, a sheet V EsTA\/AiLAeLiE eos' i,24s,9o3 I i' a slight puifingsound is observednotvvithstanding the silencing effect of the radiator.
